The Installation failed when trying to install grub-efi-amd64-signed. Then I open a shell and chroot me on the target system before updating the system. Then, I try to install manually grub-efi-amd64-bin with the parameter --fix-missing because without, everything crached lamentably. It seem to be the hash between the cdrom ??? I'v installed it via usb key with the iso file.
Oh yeah, I see the cdrom at /cdrom who contain the cdrom from the key at sda1. The checksum seem to not corresponding why ??? The iso come from your site, version : +---------------------------------------------------------------------------------------------------------------+ | Origin: Ubuntu | Label: Ubuntu | Suite: focal | Version: 20.04 | Codename: focal | Date: Thu, 23 Apr 2020 17:33:17 UTC | Architectures: amd64 i386 | Components: main restricted | Description: Ubuntu Focal 20.04 | Acquire-By-Hash: yes | SHA256: | 44fa689d816504f1c9ba27b08d46f25a4897a4f21ced7921f5a8530e32ce0b60 95 main/binary- amd64/Release | 0ddb4d5173aaebfecc84f1c2141b800e1383aa30d95551d3dc077b00edc87a53 32859 main/binary- amd64/Packages.gz | 485f21ce519cd8cbc76b74f1c8be5ecb66e6ccf7360786176dc33cce3fcd44c2 129561 main/binary-amd64/Packages | 136e603984989c1db83d4cef46881f5b197d65120c49fc718e0a81bb21a166bf 94 main/binary-i386/Release | 046ffca8fe73b0be51b4bc545534a305bcf60eeda25a0e20310d7d56aaf3c84f 30483 main/binary-i386/Packages.gz | 4af2902b57f5f0054055b4b9f7dce8cb0a4cce6f1ccaa2897f86c227e0501569 124289 main/binary-i386/Packages | d8f70ca1fe1aaab95538a2c4d45118be407c0c479a247a41b2de094041cb940a 101 restricted/binary-amd64/Release | fc10faec5274c2c42ae6b9b24c3f8357093148ded718aad9cab55975b301cdf0 28441 restricted/binary-amd64/Packages.gz | 22b7ef09670506420b66f44377fa8f706b7449589cf38067eec0798ba5863e6c 204178 restricted/binary-amd64/Packages | f51659fc018cde566f5297af01955e5749d53de3bce71c14e132e02ae6ca4363 100 restricted/binary-i386/Release | 6148b566ec8669e2a7da86674f209ef7bfb8766a5a12cc091bf942022a2b1a12 4705 restricted/binary-i386/Packages.gz | 39140436e2282ccf3691129ee086e1d7bffee745118b9fe06bd4f71d62dc7fa0 21508 restricted/binary-i386/Packages +---------------------------------------------------------------------------------------------------------------+ The result of the installation command -------------------------------------- root@ubuntu:/# sudo apt install grub-efi-amd64-bin --fix-missing Lecture des listes de paquets...
